Description: OneNAND闪存在嵌入式系统中的应用
OneNAND Flash是三星公司开发的一类Flash芯片,它克服了传统NAND Flash接口复杂的缺点,具有接口简单、读写速度快、容量大、寿命长、成本低等优点。文章从软硬件两方面介绍了其在嵌入式系统中的应用,特别是逻辑块和物理块地址的映射、读写擦操作、坏块处理、性能优化等技术。-OneNAND flash memory in embedded system applications developed by Samsung' s OneNAND Flash is a type Flash chips, which overcomes the traditional shortcomings of NAND Flash interface, a complex with a simple interface, read and write speed, large capacity and long life and low cost advantages. The article describes both hardware and software in embedded system applications, in particular logical block and physical block address mapping, read and write wiping operation, bad block handling, performance optimization technologies.
